  8. Transfer the mixture to a casserole dish and top with shredded mozzarella and provolone cheese.
  9. Sprinkle dried oregano over the top.

  11. Let rest for a few minutes before serving. Garnish with fresh chopped parsley if desired.

Notes

This casserole is naturally lower-carb without the traditional bread. For dietary adaptations, try ground turkey or chicken instead of beef, or use dairy-free alternatives for the cheese. The casserole reheats beautifully, making it perfect for meal prep. For added heat, include jalapeños or a dash of hot sauce. Serve with a crisp garden salad, garlic bread, or french fries for a complete meal.
